.SH DESCRIPTION
.PP
These routines return a string of \fBwchar_t\fR wide characters in \fIwstr\fR,
extracted starting at the current cursor position in the named window.
.PP
The four functions with \fIn\fR as the last argument return
a leading substring at most \fIn\fR characters long
(exclusive of the trailing NUL).
Transfer stops at the end of the current line, or when \fIn\fR characters have
been stored at the location referenced by \fIwstr\fR.
.PP
If the size \fIn\fR is not large enough to store a complete complex character,
an error is generated.
.SH NOTES
.PP
All routines except
\fBwinnwstr\fR
may be macros.
.PP
Each cell in the window holds a complex character (i.e., base-
and combining-characters) together with attributes and color.
These functions store only the wide characters,
ignoring attributes and color.
Use \fBin_wchstr\fP to return the complex characters from a window.
.SH RETURN VALUE
All routines return
\fBERR\fR
upon failure.
Upon
successful completion, the *\fBinwstr\fR
routines return
\fBOK\fR, and the *\fBinnwstr\fR
routines return the
number of characters read into the string.
.PP
Functions with a \*(``mv\*('' prefix first perform a cursor movement using
\fBwmove\fP, and return an error if the position is outside the window,
or if the window pointer is null.
